IMPROVEMENT IN COLLARS FOR LAMPS.

Specification forming part of Letters Patent No. 4I,L55, dated January 12, 1864.

hereby declare that the following is a full,

clear and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a side elevation showing the collar attached to a lamp and provided with a chimney and in a closed position. Fig. 2 is a vertical section showing the collar open so as to allow the lamp to be lled.

Several devices have been invented for the purpose of facilitating the filling of lamps, and among others is that described in the patent granted to T. J. Colburn, assignor to Lemuel Beers, July 14, 1863, in which a device is described which is intended to be inserted between the lamp-cap (or ferrule) which sur-l rounds the top of the oil-reservoir and the up per part of the lamp. A

This device is made in two parts hinged together, the lower part of which being screwed into the lamp cap or ferrule, and the upper part receiving the burner, which is screwed intoit in the same manner that it would have been otherwise screwed into the cap. My invention differs from'this in having the part which receives the burner hinged directly to the lamp cap or ferrule which surrounds the oil-reservoir, thus dispensing with one piece, and making the attachment more firm, while it gives the same facility for lling the lamp.

In the drawings, A is the body ofthe lamp or the reservoir in which the oil is contained.

B is the lamp cap or ferrule which surrounds the top of the glass or forms the top of the reservoir.

Gis a piece attached by a hinge to the lampcap B. This is provided with an internal screw to receive the burner D.

E is the chimney.

The piece C is attached to the cap B by a stop-hinge, which shall only admit its being opened to about the distance represented in Fig. 2, in which position it is kept by the weight of the upper part of the chimney of the lamp while the lamp is being filled. After the lamp is iilled it is returned to the position shown in Fig. I, in which position it is retained by a spring-catch, or any other device which may be desirable.

In the construction here represented the top of the ferrule B is turned out slightly at a point opposite the hinge, and a corresponding catch is formed on the part O, to slip over it and hold the part O in its proper position for using the lamp. A small projection, F, on the part C furnishes the necessary facility for raising the edge of the piece C when desired.

Having thus fully described my invention, I claimp rIhe combination of the part C with the ferrule by direct attachment, which allows the lamp to be opened sufficiently to lill it, substantially as and for the purpose set forth.

JNO. G. BEERS.
